[PLP]

If I can revisit here...

78F350 posted a diagram.
It shows 3 wires.

Now, from what I gather, and based from my testing of the switch, positions 2 and 3 are grounds and are bridged. Position 4 is for brake lights.
Then, position 1 would be for cruise control.

Am I right?

If so, where does the #1 lead to?

I am trying to understand my intermittently working, or not working, CC.

I checked the switch and it works OK. I opened it up. It looks nice and all contacts are OK.

Where to look for?

Symptoms.
Before start the green light shows up. Once started it maybe still on (if the CC switch was activated) and the CC will work as designed.
However, there are days when it would not be lit after start. I cannot activate it at all.

One more place to check is the clutch switch.


But then, even if the clutch or brake switch were faulty, I would still be able to see the CC light and turn it on or off, right? I would not be able to activate speed control, though.
Yet, it seems like it is not there on days....
